Models and Database Migrations

Software Contributor Documentation Table of Contents

Overview:

Models exist in the chroma-manager/chroma_core/models/ directory. Once a model is created, a database migration file must be generated such that the tables reflecting the model will be created in the database. The procedure below shows how to create a migration file for rsyslog as an example, but the steps are the same for all models.

1. import the model into chroma-manager/chroma_core/models/__init__.py

   from rsyslog import *
   

2. Run the schema migration from the chroma-manager directory.

   ./manage.py schemamigration chroma_core --auto
   

This will create the migration file. Optionally, this migration may be applied by running the following in the chroma-manager directory:

./manage.py migrate
